This paper deals with the results of long-term ecological and gas researches of methane distribution in soil and subsoil layers of the mine «Kapitalnaya» at the Tavrichansky coal field. The seven main spatial-temporal regularities of dangerous gas-geochemical field formation connected with the mine liquidation are determined. Authors define the geological and technogenic factors influencing distribution of dangerous methane concentration in soil of the mine field and Tavrichanka settlement.

Keywords: soil, subsoil layers, methane, genesis, migration, gas-geochemical field, regularities, factors, mine, liquidation, gas hazard.
